I am a new Hadoop developer. I want to implement an algorithm which enhances theHadoop performance in Heterogeneous environments. I tried to build and run manyversions for the Hadoop source code but the only one that I have succeeded tobuild and run is hadoop-205.

I want to know if this version is suitable to edit on it, or there is a betterversion I should use in my implementation.

Hi Salma,I have a question about your development enviroment.Did you use eclipse?I am going to use branch-1 to do some experiments on that.The thing is iwant to import the source code into eclipse and modify and build it.Seems the source code inside src pachage in branch-1 is not mavenized .So how did you build your project ? Did you do that from eclipse or commandline?
